About Temperature Conversion

Temperature is a physical quantity that expresses hot and cold. It is measured with a thermometer calibrated in one or more temperature scales. The most commonly used scales are Celsius (°C), Fahrenheit (°F), and Kelvin (K).

Temperature Conversion Formulas

Our temperature converter uses these precise formulas to ensure accurate conversions:

Celsius to Fahrenheit

°F = (°C × 9/5) + 32

For example, to convert 25°C to Fahrenheit: (25 × 9/5) + 32 = 77°F

Fahrenheit to Celsius

°C = (°F - 32) × 5/9

For example, to convert 98.6°F to Celsius: (98.6 - 32) × 5/9 = 37°C

Celsius to Kelvin

K = °C + 273.15

For example, to convert 0°C to Kelvin: 0 + 273.15 = 273.15K

Kelvin to Celsius

°C = K - 273.15

For example, to convert 300K to Celsius: 300 - 273.15 = 26.85°C

Fahrenheit to Kelvin

K = (°F - 32) × 5/9 + 273.15

For example, to convert 68°F to Kelvin: (68 - 32) × 5/9 + 273.15 = 293.15K

Kelvin to Fahrenheit

°F = (K - 273.15) × 9/5 + 32

For example, to convert 300K to Fahrenheit: (300 - 273.15) × 9/5 + 32 = 80.33°F

Common Temperature Conversions

• 0°C = 32°F = 273.15K (Freezing point of water)
• 20°C = 68°F = 293.15K (Room temperature)
• 37°C = 98.6°F = 310.15K (Normal human body temperature)
• 100°C = 212°F = 373.15K (Boiling point of water at sea level)

Temperature Conversion Applications

Temperature unit conversions are useful in many areas:

• Cooking and baking recipes from international sources
• Weather forecasting and climate science
• Medical and healthcare settings
• Scientific research and laboratory work
• Engineering and manufacturing processes
• International travel and global communications

Understanding Temperature Scales

Celsius (°C) - Used in most countries worldwide. In this scale, 0°C is the freezing point of water and 100°C is the boiling point of water at standard atmospheric pressure.

Fahrenheit (°F) - Commonly used in the United States. In this scale, water freezes at 32°F and boils at 212°F at standard atmospheric pressure.

Kelvin (K) - The SI base unit of temperature used in scientific contexts. It uses the same increment as Celsius but starts at absolute zero, the theoretical lowest possible temperature. 0K is equal to -273.15°C.

Rankine (°R) - An absolute temperature scale that uses the Fahrenheit scale's degree intervals but starts at absolute zero, like Kelvin. 0°R is equal to -459.67°F.

Réaumur (°Ré) - A temperature scale where the freezing point of water is 0 degrees and the boiling point is 80 degrees. It's rarely used today except in some European cheese and candy making.

Our temperature converter provides accurate conversions between all these scales, making it easy to translate between different temperature measurements for any scientific, professional, or everyday need.
